Workers Wednesday ended a one-day wildcat strike at one shipyard, and a stoppage at a second yard dwindled after Solidarity leader Lech Walesa urged an end to the protests.

The strikes that began Tuesday at the Wisla and Repair yards in this Baltic port were to protest the government's announced intention to close the nearby Lenin shipyard, Solidarity's birthplace.On Wednesday several hundred workers gave up their strike and took down banners at Wisla, which makes yachts and river craft, after receiving assurances that some dismissed workers would be rehired, a strike leader said.

At the Repair yard, workers rallied this morning, but it appeared their enthusiasm was waning and they would end the actions.

Defying an appeal by Walesa to end their occupation strikes, workers had remained at both yards overnight in near-freezing weather.

Last week, Communist authorities said they were closing the huge Lenin shipyard Dec. 1 because it is losing money.
